Light-walled rectangular pipe and tube from China may be covered by both a U.S. antidumping duty order (case A-570-914) and a countervailing duty order (case C-570-915). Importers of this steel product from China should carefully review scope, origin, and exporter/producer identity, as related orders also exist for South Korea and Mexico.

Scope — simplified screening examples, not full legal scope

The official written scope controls. The examples below are screening references only.

Products that may be covered (examples)

•Rectangular cross-section steel pipe and tube that may have a wall thickness of less than 4 millimeters
•Square cross-section steel tubing that may fall within the same wall-thickness range
•Welded light-walled carbon steel tubing of rectangular or square shape
•Certain quality light-walled steel pipe and tube used in structural or general applications
•Rectangular tubing that may be cut to length but still meets the thin-wall description
•Light-walled tube completed in a third country (e.g., Vietnam) using China-origin hot-rolled steel, which may be included by circumvention findings

Products that may require separate review or may fall outside this order

?Rectangular or square tube with a wall thickness of 4 millimeters or more may fall outside this order
?Round or circular cross-section pipe and tube (commonly outside a rectangular/square-specific order)
?Stainless steel or non-carbon alloy tubing may be outside scope depending on the written description
?Light-walled tube produced in a third country from non-China-origin steel may not be covered under these China orders
?Finished downstream fabricated articles that are no longer simply pipe or tube may fall outside scope

Scope control: HTS codes are screening references only; Commerce's written scope language controls whether a product is covered, and parts, unfinished, or third-country-processed items may still be covered depending on scope and circumvention findings.

Who it affects

This typically matters for importers of thin-walled rectangular or square carbon steel pipe and tube of Chinese origin, and potentially for importers of such tube completed in third countries like Vietnam using China-origin hot-rolled steel.

What the duty means

Covered merchandise typically requires cash deposits of estimated duties at entry; rates vary by exporter/producer and administrative review and can be high. Because both an AD order (A-570-914) and a CVD order (C-570-915) exist, both deposits may apply. A 0% cash-deposit rate is NOT an exemption — the order still applies and entries must be declared.

Importer checklist — how to assess your risk

☐Gather the commercial invoice with a precise product description including cross-section shape and wall thickness.
☐Collect product photos, spec sheets, and mill certificates showing dimensions and material composition.
☐Document the steel type (carbon vs. alloy/stainless) and intended use of the tube.
☐Obtain country-of-origin support, including the origin of the hot-rolled steel input, especially for third-country processing.
☐Identify the manufacturer, producer, and exporter names and confirm the specific producer/exporter combination.
☐Determine and verify the HTS classification as a screening reference only.
☐Confirm scope questions with a licensed customs broker or trade counsel rather than relying only on supplier statements.
☐Verify the current cash-deposit rate against current Commerce administrative review results and CBP AD/CVD messages before filing.

Risks to watch

⚠Circumvention or transshipment findings, such as tube completed in Vietnam using China-origin hot-rolled steel, may bring goods within scope.
⚠A scope inquiry could determine that borderline products fall within the order.
⚠Declaring the wrong exporter/producer combination can lead to an incorrect (often higher) deposit rate.
⚠Misdeclaration of origin, scope, or rate may result in penalties, retroactive duties, and enforcement action.

The same product may be subject to separate orders in multiple countries — related orders exist for South Korea and Mexico — so each origin should be reviewed independently on its own facts.

FAQ

Is there antidumping duty on light-walled rectangular pipe and tube from China?

There is an antidumping duty order on light-walled rectangular pipe and tube from China under case A-570-914, and a separate countervailing duty order under C-570-915. Whether your specific goods are covered depends on Commerce's written scope; importers should verify.

Does a 0% deposit rate mean no duty?

No. A 0% cash-deposit rate is not an exemption. The order still applies, entries must be declared, and rates may change through administrative review, so importers should confirm the current rate before filing.

Are parts or unassembled light-walled pipe and tube covered?

They may still be covered depending on Commerce's written scope. Additionally, tube completed in a third country using China-origin steel may be included through circumvention findings, so importers should verify scope and origin carefully.

Possible risk

Risk signal: Higher concern if the goods are thin-walled rectangular or square carbon steel pipe and tube of Chinese origin; a separate review is needed for wall thickness near 4 mm, non-carbon materials, and third-country processing using China-origin steel.

Bottom line: Light-walled rectangular pipe and tube from China may be covered by A-570-914 (AD) and C-570-915 (CVD); confirm scope, origin, exporter/producer identity, and current deposit rates before entry.
